Abstract
The utility model relates to a metal pipe, in particular to a metal flexible pipe. Aiming at mainly resolving the problems of falling of a pipeline and bursting of an oil tube caused by the fact that a polyamide oil pipe on a machine tool hydraulic system is not resistant to high temperature or high pressure, the utility model provides a high temperature and high pressure resistant metal flexible pipe. The metal flexible pipe comprises a metal bellows and a net cover outside the metal bellows, wherein joints are installed at two ends of the metal bellows, and a nut is connected with the joint in a threaded mode. Through tightly connecting the nut with a pipeline, the pipe doesn't fall off when temperature is high. The metal flexible pipe has the advantages of being resistant to high pressure and long in service life.
Description
Technical field
The utility model relates to a kind of metallic conduit, specifically, relates to a kind of metallic hose.
Background technique
General lathe all can adopt hydraulic system to carry out transmission, flowing of hydraulic oil adopted the nylon pipeline of plastics usually, because hydraulic system is when operation, oil temperature, oil pressure all are in than higher position, nylon tube has the characteristic of necessarily expanding with heat and contract with cold, and oil temperature expand at the jointing nylon tube and to a certain degree to cause the interface shakiness to come off when higher, nylon tube does not possess anti-high pressure ability simultaneously, and the high pressure of hydraulic oil also may cause the nylon explosion.
Summary of the invention
The utility model has mainly solved: the nylon oil pipe on the general machine tool hydraulic system does not possess high temperature resistant, high voltage bearing characteristic, and pipeline comes off, the problem of oil pipe explosion and cause, and a kind of metallic hose of high temperature resistant, high pressure is provided.
The technical solution adopted in the utility model is: metallic hose, comprise metal bellows, and the two ends of metal bellows are provided with joint, also comprise the net that metal bellows is outer.
As preferably, a nut is threaded on the described joint; Be connected with other pipelines by nut connector, can keep the sealability of pipeline, oil-proof.
As preferably, described net is the wire net.
The beneficial effect that the utility model is obtained is: closely be connected with pipeline by nut, connect temperature and can not come off; Has long characteristic of high pressure resistant life-span.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1, wire net, 2, metal bellows, 3, joint, 4, nut.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is further described.
Embodiment: metallic hose (referring to accompanying drawing 1), comprise metal bellows 2, the two ends of metal bellows are provided with joint 3, are wrapped with wire net 1 at metal bellows, dispose the nut 4 that is used to connect at the two ends of joint.
During use, the nut 4 on the swivel joint 3 makes nut 4 end outside be connected with pipeline opening, so just metallic hose can be connected on the pipeline opening.
Claims (3)
1. a metallic hose comprises metal bellows, and the two ends of metal bellows are provided with joint, it is characterized in that: it also comprises the net that metal bellows is outer.
2. metallic hose according to claim 1 is characterized in that: a nut is threaded on the described joint.
3. metallic hose according to claim 1 and 2 is characterized in that: described net is the wire net.
